FBS 189's tiny shower
I have a 189 FBS and the 2x2 shower is tiny, and being raised 8" off the floor makes it almost unusable by anyone, especially me, at 6'3".
I have done my measurments and am pulling out the shower and toilet. and will install a 43" x 24" shower pan, then reinstall my toilet turned 90 degrees, facing the shower, at the rear of the new shower pan. The tub drain will extend through the floor, and I will use a rubber pee trap from Casita ($10) then cut an inlet into the upper side of the gray water tank.
I will now have about 6'1" of standing room in a 2' x nearly 4' shower, with the toilet serving as a seat if desired. I got the design idea from my previous Casita trailer, which had an integrated shower/toilet set-up. Figure the shower pan, and new shower surround can be purchased for around $250 with pee trap and fittings bringing the total project to around $300
